2 simple java applet

Hi
I have 2 short questions about java applets.
1. when my applet comes up in the web browser, I have to click it before it will identify and fire off keyup and keydown method. (it's like i have click it with the mouse to wake it up or put it in focus) these are the methods i'm using
public boolean keyUp(Event e, int key){
     showStatus(" ");
     return true; }
public boolean keyDown(Event e, int key){
return true;}
QUESTION: Is there something special, that I have to do to make it automatically accept or see keyDown actions.
2. QUESTION 2: What is the syntax to capture key event for the Spacebar and Esc button?
For example I know that the event to catch the letter m is like this :
if(key=='m'||key=='M'){
and function key is caught like this
if(key==Event.F1){
But how do I catch the spaceBar and Escape?
Thanks a lot in advance.

hi is requestFocus() part of jdk 1.0 ?
Have you ever used it before successfully?
If so, can type a little syntax about how it works ?
and to the person who had the javascript solution could you type a little syntax about how it works ? i also tried that. i put my applet in a div container and try to give it focus. I also tried to give the applet itself a name and give it focus with
document.appletname.focus();

  • Simple java applet help

    im following the java tutorial at their web site online. I'm having problems with these simple applets:
    http://java.sun.com/docs/books/tuto...kMeApplets.html
    I compiled them fine on my other computer, but when I compiled them on the computer I am using presently, I get a problem.
    the files seem to compile fine. but when i compare them with the files online, my files that i compiled are a little less in size. when i load the applet in the provided html file, all i get is a blank gray screen. and when i move the mouse over the gray screen, it says for a split second: "load: class ClickMe not found"
    i have all the correct files...but after compiling the .java files, it doesn't work. the .class files on the web work fine. but my compiled files seem to be smaller than those on the web.
    the ClickMe.class file i compiled is 1.45 KB (1,494 bytes)
    the Spot.class file i compiled is 293 bytes (293 bytes)
    the ClickMe.class file online is 1.50 KB (1,539 bytes)
    the Spot.class file online is 339 bytes (339 bytes)

    I believe that one (or more) of these applats are currently broken - the files are mislocated, I believe. Just skip the clickme applets (unless you want to debug them yourself).

  • Why is a simple Java applet not diplaying properly in its window bounds?

    Hello, I am having difficulty displaying applets on the Mac. Here is one of the simplest applets copied exactly from the Sun java website. This applet runs fine on PCs, unfortunately, on my sister's Mac, it does not display properly. It looks like the browser reserves the proper cutout window for the applet. But then the applet does not display in that window, instead, it paints itself shifted away from that window, even covering browser's borders and toolbars.
    She is using Leopard, the Mac was bought new last year, and the browser is Firefox. She is using java 1.4, I don't want to switch that, because that is what is by default running there. Most internet users would not know to switch their java version if an applet does not show properly. So it has to show properly for any java version that may be default on a Mac.
    Here is the SSCCE:
    file HelloWorld.java:
    import javax.swing.JApplet;
    import java.awt.Graphics;
    public class HelloWorld extends JApplet {
    public void paint(Graphics g) {
    g.drawRect(0, 0,
    getSize().width - 1,
    getSize().height - 1);
    g.drawString("Hello world!", 5, 15);
    file HelloWorld.html:
    <APPLET CODE=HelloWorld.class WIDTH=850 HEIGHT=730 >
    </APPLET>

    You'll most likely get a cogent response posting to the Unix forum under OS X Technologies.

  • Simple java applet help needed

    hi, im having trouble with an applet im developing for a project.
    i have developed an applet with asks the user for simple information( name,address and phone) through textfields, i wish for the applet to store this information in an array when an add button below the textfeilds is pressed.
    client array[];
    array=new client[];//needs to be an infinate array!
    I have created the client class with all the set and get methods plus constructors needed but i dont know how to take the text typed into the textfields by the user and store them in the array.
    i also need to save this info to a file and be able to load it back into the applet.
    Could some please help! Thank you for your time.

    Better maybe redefine the idea using an data structure :
    public class client{
    private char name[];
    private char address[];
    private int phone;
    public class vector_clients{
    private client vect[];
    // methods for vect[]
    What is your opinion about ???

  • Printing problem on java applet

    Hi, I'm Korean and MacBook air user.
    I'm very not good at English, please excuse me .
    I use OS X 10.8.3 and jdk 7.
    I make a simple java applet program includes printing functionary.
    But, only browsers (Safari and FireFox) on Mac OS X  not printing font correctly.
    I use setFont() function and then drawString() function.
    If you cannot understand my question, enter the link below. I think that question is same with my question.
    http://stackoverflow.com/questions/15466060/java-app-on-mac-os-x-not-printing-fo nts-correctly
    Thank you for reading my question.

    Points/questions.
    It is a lot easier to debug these things if we can see the applet. Is it on the net? Can you give us the URL?
    Have you considered launching this applet using web start? (If it turns out to be related to security, the web
    start JNLP API has a neat way to sidestep that problem.)
    Edit 1: Deleted the entire first two paragraphs when realised you said 'always prints'.

  • Java Applet in a HTML page: failing with PLS-00306: wrong number of args

    We are trying to use a Java Applet in a HTML page. as our system needs to be able to retrieve a predefined set of data from a third party system that uses Dynamic Data Exchange Protocol (DDE) and are encountering errors from APEX and in IE itself.
    We are using JavaDde from www.nevaobject.com that enables our Java applet to interact with Windows applications (Third Party System) using DDE.
    This functionality is currently used in our Web Form 6i application and we are trying to use the same in the new ApEx application.
    We are using ApEx version : 2.1 and actually aer encountering 2 problems:
    Problem 1: ApEx failing with PLS-00306: wrong number or types of arguments in call to 'ACCEPT'
    Problem 2: IE crashes if Applet used in a complex page with several regions (1 Context, 4 Report Regions, 2 level Tabs, Links)
    This problem does not occur in the page where there is only applet and one region. In the case of complex page the IE crashes if the page is reloaded
    Test scenario:
    1- Create a simple page with the HTML region.
    2- Define the Source of the above region as follows
    <OBJECT CLASSID="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
    CODEBASE="http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#version=1,4,0,0"
    WIDTH="1"
    HEIGHT="1"
    ID="simpleApplet"
    NAME="simpleApplet">
    <PARAM NAME="code" VALUE="simpleApplet.class" >
    <PARAM NAME="archive" VALUE="simpleApplet.jar" />
    <PARAM NAME="type" VALUE="application/x-java-applet;version=1.4">
    </OBJECT>
    3- Create a simple Java applet "simpleApplet" - for the test its enough if the applet will have just the init method printing out the mesage to the console
    4- Create a Submit Button (not redirect) in Region Header and create unconditional (do not set When Button Pressed property) Page Branch to navigate to another page (the page without the applet)
    6- Run the page and Submit -
    The error below is returned by the engine:
    In our case our applet is called ddeApplet - I do not know why is ApEx passing the Applet's ID down to the wwv_flow.accept method as a parameter

    It looks like whatever HTML you're including on your page is creating HTML input form elements inside the HTML form "wwv_flow". This form is posted to wwv_flow.accept, and of course, the PL/SQL procedure wwv_flow.accept doesn't know anything these additional arguments/form elements you're attempting to POST.

  • Java Applet IIOP Call-In with Release 3C--How do we speed updownload ti

    We have successfully implemented a simple Java Applet that calls into
    Forte Services via IIOP. However, the duration of the download time for
    Applet and its required class files is UNACCEPTABLE in a typical
    INTERNET environment where 28.8K modems and multiple hops around the net
    are not uncommon. We dialed into our network at 28.8K (but no hopping),
    and found that download times varied from 1.5 - 2.0 minutes. This is
    unacceptable, even by internet standards. We have been using the
    Visigenic Visibroker product as the ORB.
    After doing some investigation, we've come up with several ideas to
    speed up download time:
    1. Figure out how to use the Visigenic components (CORBA/IIOP class
    files) that come bundled with the latest version of the Netscape
    Navigator browser, so that they don't have to be downloaded
    2. Figure out how to use ZIP files. Here's what I've read: "Since the
    introduction of Netscape Navigator 3.0, you can specify an uncompressed
    .zip file as an addition to the code base of your application. By
    specifying a ZIP file, the browser will load your applet's classes from
    a specified ZIP file before it searches the code base. This ZIP can
    improve applet download time by reducing the number of HTTP connections
    required to fetch applet code. As an added benefit, Netscape caches the
    single ZIP file so that it will not reload your applet unless the date
    of the ZIP file has changed."
    3. Figure out how to use JAR files. Here's what I've read: "JAR
    stands for Java archive. It's a file format based on the popular ZIP
    file format and is used for aggregating many files into one. Although
    JAR can be used as a general archiving tool, the primary motivation for
    its development was so that Java applets and their requisite components
    can be downloaded to a browser in a single HTTP transaction, rather than
    opening a new connection for each piece. This greatly improves the
    speed with which an applet can be loaded onto a web page and begin
    functioning. The JAR format also supports compression, which reduces the
    size of the file and improves download time still further."
    Unfortunately, we've been unable to get any of these approaches to work.
    Has any one used these or other approaches to speed up applet download
    time? Or, does anyone know of consulting firms that specialize in this
    sort of thing?
    Thanks in advance for your help.

  • Re: [Fwd: Java Applet IIOP Call-In with Release 3C--How dowe speed up d

    Hi Michael,
    We have done exactly what you describe and have avoided the slow applet
    download times. Although it can be a bit tricky, it is possible to use
    the ORB bundled inside the Netscape 4.0 browser (Visibroker for Java by
    Visigenic). Most of the code should follow Netscape's examples (on
    http://developer.netscape.com)--just remember to initialize the ORB by
    passing a reference to the current applet in orb_init() (so that you
    invoke something like orb_init(this) [assuming you are extending
    java.applet.Applet]). Pulling up the Java console within your web
    browser should help debug quite a bit (a lot of debug messages will get
    printed there the ORB is having problems).
    Netscape has just implemented the applet caching schemes you describe,
    so it probably shouldn't matter too much if you use another vendor's
    ORB (we've done this with Iona's OrbixWeb). If you use ZIP files, they
    have to be uncompressed, and I don't think that the browser will cache
    them between browser sessions. Netscape 4.0 does seem to handle
    compressed JAR files just fine and it does indeed cache them between
    browser sessions. I'd go with the JAR format anyway since the ZIP
    bundling was just a workaround until Sun got their act together in the
    1.1 JDK.
    By the way, you also might want to take advantage of the code-signing
    and capabilities APIs of Netscape if you are going to invoke methods on
    objects not resident on your web server. Otherwise, you will probably
    run into the (in)famous browser applet security restrictions and you may
    have other problems doing things like callbacks from Forte, etc.
    If you want more detail on how it works, let me know and I can post some
    examples.

    3. Figure out how to use JAR files. Here's what I've read: "JAR
    stands for Java archive. It's a file format based on the popular ZIP
    file format and is used for aggregating many files into one. Although
    JAR can be used as a general archiving tool, the primary motivation
    for
    its development was so that Java applets and their requisite
    components
    can be downloaded to a browser in a single HTTP transaction, rather
    than
    opening a new connection for each piece. This greatly improves the
    speed with which an applet can be loaded onto a web page and begin
    functioning. The JAR format also supports compression, which reduces
    the
    size of the file and improves download time still further."
    Unfortunately, we've been unable to get any of these approaches to
    work.
    Has any one used these or other approaches to speed up applet
    download
    time? Or, does anyone know of consulting firms that specialize in
    this
    sort of thing?
    Thanks in advance for your help.

  • Java Applet and MS SQL 7.0

    I wrote a Java application that connects to a local MS SQL 7.0. It works just fine. But when I converted it to a simple Java applet, then I connected to the database, an error occured: "java.security.AccessControlException:access denied(java.lang.RuntimePermission accessClassinPackage.sun.jdbc.odbc)."
    What's possibly wrong? Thanks.

    Applets have a lot of security restrictions on them and cannot do a lot of things. So connecting to Databases is one thing that an Applet cannot do without u allowing it to connect, by modifying the security policy, using the policy tool. But again, this approach will work only when the environment in which the applet is deployed is under your control.

  • Java Applet

    Very simple question here. Im very frustrated with this simple java applet right now. Will this applet at this URL display for anyone?? http://www.everythingsgood.com/Computer/IntegerCalculatorGUI.html I have been reading Java applet tutorial sites for the past 6 hours and all of them tell me the same thing. All I need is this tag
    <APPLET height="150" alt="Browser has Java disabled" hspace="150" width="450" code="IntegerCalculatorGUI.class"></applet>
    along with having the .html file in the same directory as the java.class. I have done everything excalty as described by many people and this thing still pulls up a empty box with a red X in it. What am I doing wrong? Anyone have any ideas. This is really frustrating since im 99% positive the html tag is perfect. If you want to view the calculator applet code here it is http://www.everythingsgood.com/Computer/classes.rar I have also tried to use a .jar but with no effect as well.

  • Compiling Java Applets

    Hi!
    I've had some trouble running Java Applets on my server. After some debugging I have found that it maters how and/or where they are compiled.
    I have taken a simple HelloWorldApplet and compiled on my server. Then when I try to access it from a client computer all I get is a grey box with no error message.
    I then found an applet at the Java home page where it was possible to download the .CLASS file. When I copied this file to my server it works just fine.
    So my question is: Should not a simple applet work, just because it's compiled with the latest Java Edition??
    The thing is though, when I check the box under Tools > Internet Options > Advanced, Use Java 2 v1.4.1 for <applet> every applet work just fine. But shoulden't a simple Java Applet run without this option?
    I run a MS IIS5 server and use MS IE as a browser.
    Please help me.
    /Fredrik

    Should not a simple applet work, just because it's compiled with the latest Java Edition??Don't need to compile/recompile using the latest JDK since each version is fully compatible with old versions but for advanced ones must to use "target" parameter. As example, if one applet is using regular expression API, formerly Regex API, must to compile this way:
    javac -target 1.4 yourSource.java .
    For simple applets as mentioned in your post, formerly AWT applets, don't need special care, they will work fine in any JVM, any browser any platform since this is the most primitive JVM (1.1) but in some OS the vendor supressed JVM..M$, so you must to use Java plug-in. It just supplies a Java virtual machine to run your applets/applications and in this sense becames the "native" VM. This is the better choice at all that warrants the best performance among VM's.
    At this moment you can be sure your OS was deployed without Java support of course and there aren't server constraints (applets run in client side) so maintain Sun's JVM as default and there will be no presentation faults. Moreover M$ JVM has a dangerous security bug and also is obsolete version.
    Regards.

  • Deploying a Java applet

    Here is a link to an html page that has a very simple JAVA applet to display. It does not work. I uploaded the page and the helloed.class which was created using Xcode java compiler. Other people's JAVA applets work fine, so it is not my web hosting company that is at fault. Any ideas????

  • Permission denied when I execute a unix command from within my java applet.

    Hi Gang,
    Forgive me if this is not the appropriate forum for this problem. I'm posting this problem on this forum since I got no answers on the other forum I posted on.
    I've written a simple java applet that runs a unix command and then displays some information. The applet compiles fine, and runs perfectly from the command line on my unix system.
    However, when I point a browser at the applet from my desktop PC I get the following error as taken from the java console:
    Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied (java.io.FilePermission <<ALL FILES>> execute)
    This is of course the first line in a long line of error messages. It appears that I am not able to execute a command on the unix system through my applet. I know the problem is with trying to execute a unix command since commenting it causes no error in the web browser. This is the command I'm using in java to execute the unix command:
    p = Runtime.getRuntime().exec("ps");
    Here's the html file on the unix system:
    <html>
    <head></head>
    <body>
    <appletcode=G.class height="250" width="400">
    Your browser does not support the applet tag.
    </applet>
    </body>
    </html>
    I won't list the java code since it is compiling and working on the command line. But, if you want to see it I'll provide it.
    I've done quite a bit of research on this and it seems that a great number of people have similar problems reading or executing files through java. I have yet to find a solution to this problem.
    Here are some details about my setup:
    Server:
    HP9000 running HP/UX 11.23
    Apache Web Server 2.0.35
    Java 1.5
    Desktop PC:
    Win2K Pro
    Internet Explorer 6
    Java 1.6
    If you have a solution I would be very grateful! This problem is keeping me from writing my application!
    thanks!
